I have 2 girls two and a half years apart. We did do quite a bit of a single stroller with a sling or front pack (mostly for bus rides, or shopping trips) but we also had a sit and stand stroller that we loved and used a ton. We are a one car family and do lots of walking. The sit and stand stroller was great for trips to the park, zoo and even Disneyland. My oldest daughter could stand and get in and out without help. She coulD also sit if she got very tired. It was a life saver when I went though the Denver airport with the 2 girls by myself. One nice thing was if our baby fell asleep in her infant carseat we could snap her in the stroller and she could finish her nap. When she would wake up she would be looking at her older sister and start giggling. The stroller is big, but it fits through doorways and aisles at stores. It folds pretty flat and the one we got had a sun shade for both seats and cup holders too. We got ours on sale at Babies R Us, but I have also seen them on Craigslist in good condition, if you want one, but don't think it would be worth paying full price. I hope this helps. We definitely got our money's worth out of ours.
